3.11 Relay Outputs
Each HCA series panel has 5, form C relays. 2 of the relays are dedicated to common alarm and common
trouble functions. The other 3 relays can be configured as Alarm or Supervisory functions. All 5 relay
outputs (Alarm, Trouble, and the programmable relays) carry the same voltage and current ratings. The
relays are rated 3 amps at 30VDC, power factor 0.4 - 1.0.
